Presidential Young Investigator Award: A New Partial Integration Method for Analysis of Mode Locked Semi- Conductor Lasers

这项研究的主要研究兴趣包括光电子器件高速响应的基本极限和发明超越这些极限的方法。具体地说，第一个优先事项将是展示第一个碰撞脉冲模式(CPM)锁定半导体激光器。最近，PYI和UCSB的一名研究生展示了从主动锁模激光器获得的最短脉冲减少了十倍(至560fS)。基于这项研究，人们认为进一步减少脉冲宽度是可能的。其他相关兴趣包括研究和演示能够以16Gbit/S甚至更高的比特率进行调制的高速半导体激光器、调制器和光电探测器。具体地说，研究人员参与了超晶格波导光电探测器与共面带状线的集成，以展示比以前在PIN或肖特基光电探测器中所证明的更短的脉冲响应，同时解决了被认为是这种结构固有的带宽效率乘积问题。

The primary research interest of this investigation include the fundamental limits to the high speed response of optoelectronic devices and inventing ways to surpass those limits. Specifically, the first priority will be to demonstrate the first colliding pulse mode (CPM) locked semiconductor laser. Recently, the PYI and a UCSB graduate student demonstrated a ten times reduction (to 560fs) in the shortest pulses ever obtained from an actively mode locked laser. Based on this research, it is felt that further reduction in pulse width is possible. Other related interests include the study and demonstration of high speed semiconductor lasers, modulators and photodetectors, capable of modulation at 16 Gbits/s and perhaps even higher bit rates. Specifically the investigator is involved in the integration of superlattice waveguide photodetectors with coplanar striplines to demonstrate shorter impulse responses than has ever been previously demonstrated in PIN or Schottky photodetectors, and simultaneously to solve the bandwidth-efficiency product problem that is supposedly inherent to such structures.
